We use software called SecuritySpy from BensoftwareDo u have a link to the PSS stuff I'll give it a shot
I had downloaded that one but could not figure it out did not find it very user friendly so gave up on it
EvoCam and SecuritySpy are certainly nice, but they will not help the OP. The problem is that most security systems that you buy (as opposed to network cameras or things you attach to your computer) run off boxes that don't play nice with Macs. They run servers that dish out video, hence they work with all sorts of iPhone/iPad apps designed for them or similar generic security systems. But not with Macs, or browsers on Macs.
That correct but most of those boxes are connected to the cameras via IP based cameras or a BNC connector. You just yank those connectors out of the hardware and use a video convertor like the Axis 240q that turns into IP based and you are all set
